As I was coming into Hamburg, PA I noticed something odd. The end of my hiking stick (Pole) came off leaving me with a 3" Ice spike. I feared that I might get into trouble with such a thing, so I hid it in the car and went home. Looking on line, no one sold parts for this 20+ hiking stick. My question is this, if I bought a new H.S., what type is the best? (Wood or metal.)
